I've also purchased a set of Bloodthirster wings to use on my Arctos Gorehowl on Warp Dragon conversion.
I liked the Balrog wings, but they just aren't quite as beefy as I wanted them to be. It's still a toss-up for me between the two. I'll probably end up using the 'thirster wings, though. The Balrog wings just don't really look like they'd be able to lift that sucker off the ground convincingly. I can still use them for a future DP or something.
In addition, I picked up some bits from
today that I'll need to make him.
Picked up the bloodthirster helmet from the Wrathmongers kit for him as well as the icon of Khorne as his weapon instead of a spear (maybe, not set on that) , along with some axes for my skullcrushers-as-bikers champions.
